SAFE TY-LAMP.

Specification of Letters Patent.

Patented Jan. 12, 1909.

Application filed February 6, 1908. Serial No. 414,579.

To all whom it may concern:

Be it known that I, NICKOLAS B. Irromro, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Safety-Lamps, of which the following is a specification.

The object of my invention is to provide a new and improved safety lamp, and to this end the present invention consists, of a lamp, of a safety device for preventing the contents of a lamp from exploding, in the combination of parts, and in the novel features of construction, all as fully herein described and claimed.

In the accompanying drawing, which illustrates applications of my invention, Figure l is a part elevational view and a part sectional view of a lamp embodying my invention; Fig. 2 a vertical sectional view particularly showing one form of safety device and the manner of attaching the same to the font of the lamp; Fig. 8 a section taken on line 3-3 of Fig. 2; and Fig. 4 a broken vertical sectional view showing a modified form of my invention.

Referring to the drawing, 1 designates the font of a glass lamp of the usual construction, and 2 the neck thereof. My invention, however, is not limited to the employment of the particular glass lamp illustrated, for it includes lamps of diflerent styles than that shown, and made of metal or other suitable material. Owing to the simplicity of construction and the cheapness in the cost of manufacture, the safety at tachment or device for preventing explosions may be employed in lamps of the less expensive grade and those which are so generally used.

The safety device comprises a tube or cylinder 3, having an upper open end and aclosed bottom. This tube or cylinder 3 is provided with rows of small upwardly inclined openings 41:. The form of the small openings l, as illustrated, while readily permitting the passage of oil or other liquid from the tube into the font, will aid in preventing air that may enter the top of the tube from rushing through said openings. In the form of Fig. 2, the tube 3 is formed integral with a ring or collar 5. In

the form of Fig. 4 the said ring or collar is a separable member.

In both forms the ring-member 5 is internally threaded as shown at 6 and is formed with a depending annular flange 7. The ring is adapted to be applied to the neck of the font and secured thereto by plaster or other suitable material 8, as shown by Fig. 2.

In the form of Fig. i, the upper end of the tube is formed with a small inwardly projecting flange 9 adapted to be secured to the ring-member by means of solder. A piece of wire-gauze l0 surrounds the tube and covers the openings l. The perforated wire-gauze covered tube extends down into the font of the lamp, as particularly shown by Fig. l, and is permanently secured there to by means of the ring or collar-member 5.

The lamp-burner is seated upon the ring 5, and the wick of the lamp, not shown, extends down into the perforated tube.

lVhat I claim is:

1. The combination with a lamp having a fluid containing font provided with a neck, of a safety device consisting of an integral structure comprising a tube and a ringmember, said tube closed at its lower end and open at its upper end and formed with a series of small upwardly inclined openings, said ring-member formed with an in ternally threaded portion adapted to engage a burner and 21. depending flange secured to the neck, and a wire gauze surrounding the tube and covering the openings thereof.

2. T he combination, with a lamp having a fluid containing font provided with a neck, of a safety device therein, comprising a tube closed at its lower end and open at its upper end and formed with a series of small upwardly inclined openings, a ring-member supporting the tube and secured to the neck, said ring-member having an internally threaded portion located within the neck and adapted to engage a burner and having a depending flange located on the outside of the neck, and a wire gauze surrounding the tube and covering the openings thereof.

3. The combination, with a lamp having a fluid containing font provided with a neck, of a safety devlce therein, comprising a tube closed at its lower end and open at its upper end and formed with a series of small upwardly inclined openings, e ringmember- ,lntestilnony wheneofl affix my signature su zipogting thebtubie and secured 't' thhgdz, in presence oftw'e Witnesses;
